I'm gonna disagree with the top box thing based solely on my own personal experience.Like you, I had the wobble ( 2017 V1K) with full luggage, stock tires (Bridgestone T30s 40 psi R/36 psi F) with about 5,000 miles on them, and a VStream sport/tour screen. It started at about 116 mph/186 kph (indicated).(disclaimer: Professional on a closed course) Decided I needed to find a solution, so without changing anything else, I removed the panniers, but left the top box on (OEM/ Givi V47), and tried again.I did not experience any wobble, even at 120 mph/193 kph. I did not try to go over 120 mph, but felt like I could have done so safely.As always, YMMV.For reference, I am 6'0"/182 cm tall, and 190 lbs/86 kgs.Keep your grip neutral on the bars, your arms relaxed, and ease off the throttle when you feel a wobble. Don't do anything abrupt, and never try to stop a wobble using your strength. You will fail.

Yesterday I also did a short test on a straight highway with SPORT setting, panniers, no topbox.I'd say I felt more safe than with MY 15, but the test confirmed to me that high speed is not the ideal habitat for BigV.

agreed just this weekend at 166Kms/H showing on my Garmin GPS the front felt very light.Forgot to mention since my gig at 155 Kms/h without any issues I have added the Powerbronze beak so this time at 166 Kms/H I felt the front light

Talk about wind. this bike is like a sail boat on the Confederation Bridge from Prince Edward Island to New Brunswick with side winds of 60 K this bike wants to go with it. On the way back from N.B. passing a passenger bus at 130 Km/H in a marsh area just before the bridge I was riding sideways to keep the bike going forward. It didn't happen with my Kawi Voyager 1700 at 906 Lbs that for sure. C :034:an't wait for September windy rain here in the Maritimes region it look like is going to be a lot of fun

Strong, gusty winds in this part of the world today. Despite a big screen (Givi Airflow) and an empty 47 litre topbox (no panniers though) I didn't notice anything out of the ordinary even at motorway speeds.

The Confederation Bridge is the exception. I had my worst crosswind ever over the Strait on a V 650 with V35 bags and a tall screen. All I could do to keep the bike in it's lane. I may have been the last bike across that day as about 20 minutes later the bridge was closed to high sided vehicles and motorcycles. The Prairies in a cross wind are a cakewalk compared to the Bridge, as is the Tantramar Marsh.

Glad your safe mate, I had a high speed wobble years ago on my R1 and can confirm its pretty scary. Personally I got the high speed riding out my system a long time ago, maybe because I have 3 girls. For me its all about the corners

My experience with a shimmy from the front end has always been a tire pressure problem. To test the phugoid oscillation problem, I accelerate to a speed close to where I experienced the shimmy, close the throttle and release the handlebars. As the bike decelerates, sometimes it would start to oscillate, and so I knew it was repeatable. I tried changing the tire pressure a few psi down first, and see what it does. Also, ensure the rear tire pressure is correct for the spec. Usually I have found an over-inflation.
